I lasted 4 weeks in this warehouse conversion before having to break lease. There are very bad soundproofing issues here. My apartment was on level 1. 

Be prepared to hear every sound from your neighbours, both upstairs and on the sides of the apartment - conversations, TV, music, doors slamming, intercoms. On day 3, my neighbour came and told me he could hear my music and explained how bad the walls are here, he also told me he could hear me talking and have meetings. There is no privacy, or peace and quiet. The apartment also backs onto an alley with very, very early garbage collections through the week. 

This was an expensive lesson for me. Take as much time as possible during inspections and try to do it at night when people are at home making noise.
